J. Rick. - Nord. J. Bot. 7: 553-568. Copenhagen. ISSN 0107-055X.
The type species of Polyporaceae (Aphyllophorales) and of other related genera, i.e.
Irpex, Grammothele and Theleporus, described by J. Rick were studied. Of the 938
names of species or varieties 34 are invalidly published and 21 are synonyms.
Nineteen type specimens were not found and 4 were sterile. Four species were
respectively assigned to Datronia, Steccherinum, Trechispora and a cyphellaceous
fungus, and were left without specific determination. The following new combinations are proposed: Aporpium substuppeus, Ceriporiopsis latemarginata, Inonotus
micantissimus, Junghuhnia polycystidijera, Perenniporia piperis, Phanerochaete furfuraceo-velutinus, Skeletocutis roseolus and Tvromyces atro-albus. Two new species
are described: Ceriporiopsis lowei and Gloeodontia americana.

Introduction
zyxwvutsr
The Austrian-born jesuit Johann Rick described a large
number of polypores, most of them collected in the environments of Ssio Leopoldo and SBo Salvador (Rio
Grande do Sul State, Brazil) where he held a professorship in theology and undertook his mycological research. In order to obtain a comprehensive notion on
the polypore flora of Southern America it was deemed
advisable to carry out a study of Rick’s type collections
most of which are extant at the Herbarium Anchieta,
Sio Leopoldo (PACA). During a three day visit to that
herbarium the author was able to revise these collections. A proper selection of types and other specimens
was later studied in the author’s laboratory. The study
also included those specimens assigned to Irpex Fr. and
other genera related to the Polyporaceae. A few type
collections kept in other herbaria were also investigated. After Rick’s death in 1946, B. Rambo arranged
his herbarium and published Rick’s monograph on the
Rio Grande d o Sul fungi which appeared in Iheringia
Bot. no. 2 , 4 . 5 , 7 . 8 . and 9 between 1958 and 1961; un0
fortunately, he failed to update the nomenclature or typify many names.
The fungi are listed alphabetically according to the
generic and specific epithets followed by a reference to
where they were published. Specimens are cited with
their present PACA’s number as Fungi Rickiani no.
(FR). followed by the place and date of collection and
any indication, if present, of it being the type. General
locality of most specimens, i.e. Brazil, Rio Grande d o
Sul State, is neglected unless of different origin, and so
are the ‘legavit’ and ‘determinavit’ notes which always
correspond to Rick. Other notes on the original label
are also quoted to aid tracing the specimens studied. No
other indications, such as Rick’s notes on the specimens’ features and/or descriptions are added unless
necessary for justifying lectotypification. When lectotypes are designated the following formula is employed:
‘selected lectotype’. Specimens of previously published
Rick’s new species, cited afterwards (Rick 1959, 1960)
as types are here considered as lectotypified by him.
This list does not include the study of species and va-

rietal names erroneously assigned to Rick by himself
and previously published by Lloyd, with whom Rick
maintained a fruitful correspondance. Even if they are
validly published such specimens correspond with those
cited by Lloyd for his species.
Measurements and drawings were made from freehand sections mounted in 1% aqueous phloxine solution in 5% KOH solution. Color notations were made
in accordance with Maerz and Paul (1930). All herbarium abbreviations are as given by Holmgren and Keuken (1974).

Daedalea latemarginata Rick (1960: 263)
Holotype FR 20230, S. Salvador, 1943: “Junio 1943”.
= Ceriporiopsis latemarginata (Rick) Rajchenberg
comb. nov. (basionym: Daedalea latemarginata Rick
(1960: 263)).
Fruitbody orbicular and resupinate, later fusing and
with reflexed margins, up to 7x6X0.2 cm, loosely attached to the substratum, contracting when dry; white
when fresh, straw to light cinnamon when dry; light, but
rigid when dry. Margin distinct, wide, slightly lobate.
Hymenial surface at first merulioid, developing pores,
teeth or ridges; pores 1.5-2 per mm, varying from round
typical ones to daedaloid and also irpicoid. Context up
to 0.4 mm thick, tubes up to 1.5 mm long, both concolorous with the pore surface.
Hyphal system monomitic. Generative hyphae with
clamp connections, 2.5-5 pm diam., with thin but distinct hyaline walls in the subhymenium and the dissepiments (Fig. 1) and with thickened ones in the context and a few in the dissepirnents; the latter with few
clamps and may be confused with skeletal hyphae

Remarks: the species is distinct by its small, broad,
ellipsoid spores, wide pores, irregular hymenial configuration and generative hyphae with thickened walls. C.
mucida (Pers.: Fr.) Gilbn. & Ryv. is different because
of its smaller pores and spores and the lack of generative hyphae with thickened walls (cf. Domaliski 1972).
I have been unable to find any similar species among
those described in Poria Pers. and Tyromyces Karst.
(Lowe 1966,1975). A small specimen of this fungus was
gathered recently in Argentina (BAFC 30428, Buenos
Aires, Campana, INTA Delta, leg. M. Rajchenberg and
J. E. Wright 3858, 16.1V.85).
Daedalea unicolor Bull.: Fr. var. ochracea Rick (1937~:160)
Selected lectotype FR 15630, sub Daedalea ochracea
Kalchbr., Sudafrika, leg. Witz: “Africa do Sud, Missao
do Boromos, leg. Eng. Witz, 111-1909”.
= Datronia Donk sp.
Fruitbody effused-reflexed, 7X2X0.2 cm, sessile, annual. Pileus tomentose, zonated with dark buff and
black zones. Context chestnut with a black line under
the tomentum. Pores 2.5-3 per mm, round to somewhat
elongated.
Hyphal system dimitic with clamped, thin-walled generative hyphae, 2 4 pm diam., and light chestnut skeletal hyphae 2-S(7) pm diam. with walls up to 1.5 pm,
mostly with a visible lumen. Spores cylindric, hyaline,
9-12-(13)~4-5 pm, IKI+, acyanophilous.
Remarks: though Rick (1937~)presumably had Daedalea ochracea Kalchbr. in mind as he stated in the original envelope, formally he validated a new variety for
Daedalea unicolor Bull.: Fr. (= Cerrena unicolor (Bull.:
Fr.) Murr.). D. ochracea is a synonym of Polyporus
meyenii fide Ryvarden (Ryvarden & Johansen 1980).
Though the sample is a large one, it is somewhat
eaten by insects either in the upper surface or the hymenophore. Nevertheless, the spore and hymenial features
are clearly discernible and key out in the genus Datronia. The specimen is different from the known species
of this genus on account of the pore and spore size. D .
mollis (Somf.: Fr.) Donk exhibits larger, angular pores
1-2 per mm, a white lower context and smaller spores,
7.5-1OX2.54 pm. D . stereoides (Fr.) Ryv. has smaller
pores, 4-5 per mm and the fruitbody is rarely reflexed.

Irpex albo-luteus Rick (1959: 189)
Fomes palustris Rick (1960: 208)
Holotype FR 15866, Typus.
= Probably Coriolopsis rigida (Berk. & Curt.) Murr.
Rick (1960) refers this collection from Brazil, Taquaremb6, 1935, but no indication of this was found in the
PACA’s envelope or on the original label, which only
bears the specimen’s name, presumably written by Rick
himself. This specimen is scant and weathered and a
correct determination could not be made.
I also studied the specimens cited by Rick (1960)
other than the type: FR 15786, Taquaremb6, 1935: “In
ligno frondoso, no. 1733, Poria suberis?”, and FR
15792: “In ligno frondoso, no. 1725”. Both are Phellinus contiguus (Pers.: Fr.) Pat. FR 15792 also contains a
manuscript description of the fungus, probably written
by Rick himself, which is identical with that published.
Nevertheless, as Rick formally designated FR 15866 as
the holotype of the species, no legal argumentation
concerning Rick’s intentions can be sustained.
Not validly published since the nomenclatural type was
not indicated in the protologue. No specimen was found
at PACA under this name.
Irpex amhiguus Peck var. barbiformis Rick (1959 188)
Not validly published since the nomenclatural type was
not indicated in the protologue. I found all the specimens cited by Rick (1959) but none of them had any
indication of the varietal name. Specimens FR 16611
and 19613, both sub Irpex ambiguus Peck, Marcelino
Ramos, 1935, were studied. They represent specimens
close to Metulodontia nivea (Karst.) Parm. differing in
their odontioid hymenophore (not grandinoid as in European specimens), narrower ellipsoid spores, 4X 2-2.5
pm and undetected gloeocystidia. The cream to pale
yellowish hymenophore exhibits rhizomorphs.

Nard. J. Bat. 7 ( 5 ) 1987
The sample is small, 3 ~ 0 . 7cm and represents a resupinate fungus with elongated pores. The hyphal system is
typical of the species but has a very good development
of the skeletal hyphae; generative hyphae are slightly
thick-walled and typically hyphodontioid. Spores are
555
Fruitbody resupinate, adnate, 8 . 5 ~ 2 . 5cm, irpicoid,
grandinoid between the aculei; margin indeterminate.
Aculei up to 1.3 mm long, irregularly scattered, more or
less solitary, 2-3 per mm, crowded, up to 5 per mm,
inclined with regards to the substrate, more or less
ceraceous in consistency, covered by a pruina. Context
up to 0.5 mm thick. Hymenial surface with a gossypine
aspect, cinnamon or toast (MP 13F8).
Hyphal system monomitic. Generative hyphae
2.54.5 pm diarn. with (generally) thickened melleous
walls, with a clamp at each septa or simple-septate.
Toward the substratum hyphae exhibit both kinds of
septa (Fig. 5), but in the subhymenium and hymenium
they are mostly clamped and so are the basidia and
basidioles (Fig. 6). Sometimes hyphae widen up to 7
pm. In the subhymenium hyphae are short-celled.
Mature basidia not seen. Basidioles cylindric to claviform, 7-12x45 pm, clamped at the base. Spores ellipsoid, with a flattened side, 4.5-5.5xs3.5 pm, hyaline, thin-walled, IKI+ , acyanophilous (Fig. 7). Cystidia cylindric, slightly clavate or with a slightly tapering
apex, 30-lW190~5-9 pm, clamped at the base, with
thickened walls in the middle portion, with a homogeneous content (Fig. 8).
Associated with a white wood-rot.
Remarks: it is with some reluctance that the species is
included in Phanerochaefe Karst. as in this genus basidial septa and subhymenial hyphae are devoid of
clamps, which are mostly restrained to the subicular
hyphae. Nevertheless, hyphae are thick-walled and with
a melleous colour, and cystidial and spore shape are
characteristic of many species of the genus. This species
is distinct on account of the irpicoid hymenium and its
peculiar hyphal system and does not fit any of those
recorded by Burdsall (1985) for the genus. Eriksson et
al. (1978) have stated that “possibly there may exist
fibulate species, which in other respects are so close to
Phanerochaete that they must be included, but so far we
don’t know of such species”. P.furfuraceo-velufinus fits
very well into this picture; only the occurrence of other
similar species will allow us to decide whether they
ought to be placed in a different genus.

broadly ellipsoid, 5 4 x 3 4 pm, and terminal globose

incrustations on the hyphae and cystidioles (as observed
in subtropical specimens), and the presence of cubic/

Irpex hydneus Rick (1959: 190)
Not validly published since the nomenclatural type was
not indicated in the protologue. Maas Geesteranus
(1974) transferred the species to Steccherinurn S. F.
Gray where it certainly belongs, but as the new combination was illegitimately made a new name was provided by Hjortstam and Bononi (1986), viz. Steccherinum subochraceum, as suggested by the ICBN Recommendation 72A. For a description see Maas
Geesteranus (1974) and Hjortstam and Bononi (1986).

S. Leopoldo, 1933: “In ligno frondoso, no. 984”.
= Hyphodontia spathuluta (Fr.) Parm. vel aff.
Hyphal system and cystidia are typical for the species
but spores slightly differ in being subglobose, 4.55 X 4 4 . 5 pm and not ellipsoid to broadly ellipsoid as in
typical specimens.
lrpex microdon Rick (1959: 187)
Holotype FR 16619, S. Salvador, 1943: “18.IV.1943”.
= Steccherinum S . F. Gray sp.
Macromorphologically the hymenophore of this specimen resembles that of S. cremeoulbum Hjortstam
(1984), presenting short aculei with fimbriated tips that
vary from grandinoid to odontioid, but differs in being
easily detachable from the substratum (actually the
original envelope only contains the fungus with no substratum attached to it) and by presenting a mycelial
margin with rhizomorphs. Microscopically it differs in
its clamped generative hyphae and its cylindric spores
3 . 5 - 4 . 5 ~1.5-2 pm. Cystidia are only present at the tips
of the aculei. S. fimbriatum (Pers.: Fr.) J. Erikss., to
which the species may also be related, has been reported from the same type locality (Hjortstam & Ryvarden
1982). However, S. fimbriatum is a more dark ochraceous species with a tough consistency and with ellipsoid
spores, 3.2-3.5-(4) X (2)-2.2-2.5 pm.
Probably this represents a valid species but more material should be studied before making a decision in this
sense.

Spores in this specimen are ovoid ellipsoid, echinulate,

0.5-(1) pm long (Fig. 15). Hyphal system is monomitic
with clamped generative hyphae, 1.5-3 pm diam.,
which may present swollen portions up to 5 pm wide.
The species is different from other hydnoid species
described in the genus (Jiilich 1976) on account of its
larger spores.
Other specimens cited by Rick (1959) and gathered
after the publication date were not studied but might
help to better understand this species.
Irpex tomentoso-cinctusRick (1959 190)
Not validly published since the nomenclatural type was

“In arbore adhuc stante”, also contains a label with a
description identical to that published by Rick. FR
16663, Sta. Maria, 1936: “In arbore adhuc stante”, is
seemingly a portion of the preceding.
= Hyphodontia spathulata (Fr.) Parm. vel aff.
The hymenophore vary from poroid-lacerate to irpicoid. Spores are subglobose, 5 x 4 pm. Typical acuminate cystidia were very few.

Remarks: the species is distinct in the genus on account
of its larger spores and the lack of pseudo- or skeletocystidia. Hydnum pyramidatum Berk. & Curt., from
Cuba, which probably belongs in Gloeodontia Boidin
differs in its monomitic hyphal system, its smaller
spores, 5 4 x 6 5 pm, and the uncertain presence of
gloeocystidia (cf. Burdsall & Lombard 1976).

Rick (1932) described a fungus with “. ..dentibus primitus porosis deinde laceris compressis.. .”. Unfortunately, although the principal microscopical features are
well preserved, macroscopically it is quite difficult to
confirm Rick’s observations as all the material is badly
broken and only small fragments are available for study.
In the larger fragments teeth up to 1.3 mm long could be
seen but they are mostly crowded and their relationship

The name was first published ‘ad interim’ by Rick
(1907); according to the ICBN Art. 34.l(b) this should
not be considered a valid publication. Later, Rick
(1928) mentioned the species and stated the type to
come from Sfio Leopoldo, but did not point out at which
herbarium it was kept. Thus Rick (1935b) is considered
the date of valid publication. Rick (1960) cited specimen FR 20417 which was not found at PACA but FR
20470 with similar data: Tupandi, IX.1945, leg. and det.
Rick: “Pol. cartilaginosus Rick ?, nullus typus exitit,
solum av est photographia”, “Intus zonalis albus tenue
brunascens. Pol. cartilaginosus Rick?”, “Polyporus
fusco-mutans Lloyd?, Natal, Sept. 1945”. The three
separate labels clearly suggest that FR 20470 is not the
type, which is presumably lost. The specimen is sterile
and undeterminable. Hyphal system is trimitic looking
very much like that of Polyporuspalustris Berk. & Curt.
No specimen under this name was available either
from Herb. Lloyd (BPI) or from FH.
A collection was found, FR 19778, sub Poria foetens

Polyporus farinosus Rick, sub Polyporus cartilaginosus Rick
(1907: 85)
The name was published by error and ‘ad interim’ as
Polyporus cartilaginosus Rick, for which reason it
should be considered as invalidly published (q.v. P.
cartilaginosus Rick). It is also an illegitimate name as it
is preoccupied by Polyporus farinosus Bref. (Brefeld
1889) for which reason Saccardo and Traverso (1911)
gave it a new name, viz. Polyporus rickianus Sacc. &
Trav., which was validated the following year (Saccardo
& Trotter 1912). Lloyd (1915) validly published the
name, but it is a nom. illegit. for the above given reason. Rick (1928) made reference to the species in Rick
(1907) and Lloyd (1915) and stated the type was in
Lloyd’s Herbarium. Such material, BPI Herb. Lloyd
no. 13309, Brazil, leg. J. Rick: “odor farinae”, represents the specimen of the photograph in Rick’s original
description (Rick 1907, p. 85, Tab. IV fig. 4) and is to be
considered the type of P. farinosus Lloyd and the selected lectotype of Polyporus rickianus Sacc. & Trav.
This specimen is Trametes ectypus (Berk. & Curt.)
Ryv., as annotated by Ryvarden.

Fruitbody lignicolous, annual, dimidiate, light, Pilei imbricate, up to 3X2.5X1 cm each, strongly convexed
downwards, juxtaposing the tubes with the pileal surface of the lower fruitbody, leaving the hymenophore
mostly hidden except relatively small portions that keep
growing; the pileal surface appears then with a nodular
aspect as if it were sterile mycelium (Fig. 16). The exposed pilei are small and surrounded by a distinct margin, which is more evident in the lower portion. Pileal
surface matted-tomentose to somewhat hispid, azonate,
cinnamon in the portions with the exposed hymenophore, rusty-brown and glabrous in the others. Context
up to 0.5 cm thick, cinnamon, with the upper portion
soft, substuppeous and becoming firmer downwards;
some fruitbodies exhibit a discontinuous resinous zone
in the lower context. Tubes up to 0.5 cm long, dissepiments cinnamon but hymenial surface with a grayish
tint, light woody in consistency. Pores 1-2 per mm, angular.
Hyphal system dimitic. Generative hyphae with
rather scant clamp connections, some typically of the
hammer type (Fig. 17), 2-4 pm diam. with hyaline to
melleous, slightly thickened walls. Skeletal hyphae only
present in the lower context and in the dissepiments,
3.5-5 W r n in diam. with thickened, melleous to light
chestnut walls, not branched, mostly with a distinctiumen (Fig. 18).
Basidla inflated and ovoid, with four longitudinal

Remarks: Polyporus gregarius was invalidly published
by Rick (1940b) because a latin diagnosis was not given.
Later (Rick 1960) he validated the name by providing a
latin diagnosis, a reference to the original description
and by citing the type, which is the only specimen extant
at PACA. The note that the tvoe comes from Vila Paperi must certainly be an error as neither in the PACA’s
envelope nor in the original label that locality is mentimed.. The general description, consistency, colour,
pileal features and hyphal system in P. gregarius were
found to come close to Polyporus substuppeus Berk. &
Curt. (cf. Lowe 1975. Ryvarden 1984). The holotype of
this species was studied (K, Brazil trail no. 123) and the
following features were ‘similar to those present in P.
gregarius: nature of the pileal surface, consistency,
. pres.
ence of a resinous zone in the lower context; hyphal systcm with presence of hammer like clamps in the generative hyphae (Fig. 21) and melleous to chestnut skeletal
hyphae. and in similar shaoe of spores with abundant
or& contents (Fig. 22) whiih are sbmewhat smaller, 57 x 4 4 3 pm. P. substuppeus is different in the general
morphology of the fruitbody, which is not strongly convex but only slightly so. in the pore size, 2-4 per mm,
and in the cartilaginous consistency of the tubes. Unfortunately. mature basidia could not be seen with cer-
tainty but only clavate basidioles which are scant in a
mostly collapsed hymenium. Nevertheless, all other vegetative features are identical with those of P. gregarius
for which reason the new combination in Aporpium
Bond. & Sing. is proposed. The particular morphology
of P. gregarius seems atypic and should not b e given
much importance.
Polyporus subreflexus Lloyd (1919) from the Philippine 11s. and its synonym Polyporus hiascens Lloyd
(1922) from S. Leopoldo, Brazil have similar spores but
differ in their effused fruitbodies with decurrent and
elongated, irregular pores, with a relatively small reflexed portion (for a description see Setliff & Ryvarden
1982).

bambusicola Rick, “In Tagnaro, S. Leopoldo, Rio
Grande do Sul, 1933, det. Rick”. This has the same
features as FR 18570 but its spores exhibit a more
distinct dextrinoid reaction.
I am of the opinion that FR 18570 pertains to a
species close to Phellinuspunctatus but it is not the same
due to the presence of setae. Lowe (1966) pointed them
to be “usually absent, or scattered and scarcely projecting” but they failed to be found in the numerous specimens at BAFC coming from the NE provinces of Argentina and Southern Brazil. David et al. (1982) recently described P. pseudopunctatus, similar to P.
punctatus, differing by exhibiting subventricose setae
15-30x9-10 pm, different cultural features and a
smaller amount of styryl-pyrones. A more detailed
study of the numerous names and their types proposed
for P. punctatus, and summarized by Lowe (1966)
should be made to better understand the species complex around this species.
Wright and Deschamps (in Wright & Blumenfeld
1984) incorrectly changed the name of the species to
Phellinus rickianus assuming the combination in Phellinus was preoccupied by Phellinus bambusarurn (Pat.)
Pat. This is not the case, as the correct epithet published
by Patouillard (1900) is Phellinus bambusinus (Pat.)
Pat., based on Polyporus bambusinus Patouillard
(1891). Under the name Phellinus rickianus Wright &
Desch., Wright et al. (in press) have described a fungus
gathered in the Argentine NE subtropical province of
Misiones which does not fit the lectotype of Poria bambusarum Rick. It presents a resupinate-pulvinate habit
of growth with a distinct sterile margin, and microscopically is distinguished on account of its hooked setae and
its globose dextrinoid spores. This species has been
described as new in a different paper (Rajchenberg
1987).

Lowe (1963) had already indicated a relationship with

Poria cinnamomea has pores 4-5 per mm, setae 253 0 x 6 7 pm and cylindric spores with no tapering ends,

Phellinus ferreus, though somewhat differing because of

Poria echiiospora Rick (1960: 277)
Not validly published since the nomenclatural type was
not indicated in the protologue.
A specimen was found at PACA on which the species
was certainly described, viz. FR 20781 sub Hymenogramme echinospora Rick, S. Salvador, 1944, typus,
leg. and det. Rick: “Poria”, and with a label with a
diagnosis almost the same as published by Rambo.
= cf. Asterostroma cervicolor (Berk. & Curt.) Massee.
Poria hirsuta Rick (1960: 273)
Remarks: the species comes close to Poria subvermispora Pil. as already stated by Lowe (1966) who certainly
studied a duplicate of one of the precited collections at
FH. P. subvermispora differs in its wider pores, 2 4 per
mm, its generative hyphae with somewhat thickened
walls, by lacking cystidioles and by its slightly larger
spores, 4.5-6~1-1.5 pm (Fig. 34) (cf. Lowe 1966, Gilbertson & Ryvarden 1986).
Poria homaema Berk. var. pallida Rick (1960: 278)
Not validly published since the nomenclatural type was
not indicated in the protologue.
Two specimens, sub Poria homaema Berk., were
found at PACA which have labels with this variety
name, viz.:
FR 20461, S. Salvador, 1943: “var. pallida Rick,
8.VII.1943” and a latin diagnosis. It probably represents the material on which the variety was described.
The specimen is permeated by hyphomycetes and its

Diplomitoporus lenis (Karst.) Gilbn. & Ryv. presents

system with skeletal hyphae.

Poria incrustans Berk. & Curt. var. terrea Rick (1960:270)
Not validly published since the nomenclatural type was
not indicated in the protologue. One specimen was
found at PACA under this name: FR 18573, S. Leopoldo, 1932: “In ligno frondoso” and with a latin diagnosis, the same as published by Rick. It is Trechispora
regularis (Murr.) Liberta.
The other specimens cited by Rick were not determined at the varietal level.

Poria laetifica Peck var. crassa Rick (1937b: 145)
Selected lectotype FR 18576, S. Leopoldo, typus: “In
ligno frondoso, no. 1614”.
Sterile. Resupinate, pores 6 per mm; hyphal system
dimitic with clamped generative hyphae and skeletals,
some with incrustations that dissolve in 5% KOH. Indeterminable.
The publication as Poria laetifica Rick must be an
error since Rick himself referred to Saccardo’s Syllogue
Fungorum 6: 300, 1886, where the combination Poria
laetifica (Peck) Sacc. was published.
Poria lamellosa Henn. var. flavescens Rick (1960: 280)
Not validly published since the nomenclatural type was
not indicated in the protologue. No specimen under this
name was found among Poria lamellosa collections at
PACA.

the pyriform spores described by Rick but they are
variable in size and are of uncertain origin.

Poria hyalina Berk. var. macrospora Rick (1960: 271)
Not validly published since the nomenclatural type was
not designated in the protologue. Two cited specimens
were studied:
FR 18624, S. Salvador, 1939: “In ligno frondoso,
October 1939”: = Schizopora paradoxa (Schrad.:Fr.)
Donk.
FR 18658, Sta. Maria, 1935: “In ligno frondoso, no.

Not validly published since the nomenclatural type was
not indicated in the protologue. A specimen was found
among those cited by Rick under the type variety, viz.
FR 18783 sub Poria membranicincta Berk., S. Leopoldo, 1939: “var. megalospora Rick, Nov. 1939”,
which is perhaps the specimen on which the variety was
described. This is Schizopora paradoxa (Schrad. : Fr.)
Donk.
Poria micantissima Rick (1960: 287)
Holotype FR 20691, S. Salvador, 111. 1944: “In Nectandru mortua”.
= Znonotus micantissimus (Rick) Rajchenberg comb.
nov. (basionym: Poria micantissima Rick (1960: 287)).
Fruitbody annual, resupinate, 10X4X 1.4 cm; margin
regular, light fulvous. Hymenial surface dark sienna to
gray chestnut. Pores round, 5-7 per mm. Tubes oblique,
up to 1.4 cm long. Context almost absent, tubes dark
fulvous. Consistency woody hard. General aspect of a
Phellinus QueI. species but lighter in weight.
Hyphal system monomitic. Generative hyphae with
simple septa, 3-5 pm diam., with yellowish to chestnut,

slightly thickened walls. Setal hyphae abundant in the
dissepiments, 160-300-(400) pm long, 10-15 pm wide
but swelling up to 25 pm in 5% KOH sol., with dark
chestnut walls up to 4 pm thick, tapering towards the
ends, not protruding into the pores or rarely so (Fig.
35). Hymenial setae lanceolate with a ventricose base,
20-32x5-9 pm, scant and in some sections totally absent, apparently found only in the young pores and in
the pore mouths (Fig. 36).
Basidia and basidioles present but partially collapsed
and measurements are not representative. Spores (?)
globose to subglobose, 10-13x8-12 pm, apiculate, with
slightly thickened walls, hyaline to slightly melleous,
with abundant oily contents, IKI+, acyanophilous (Fig.
37).
Poria ramentacea Lkrk. 8z Br. var. epipolyporeaRick
(1937b 149)
Selected lectotype FR 18668, sub Poria ramentacea,
Pareci, 1936: “In polyporo gilvo, sp. 2x2.5 pm, no.
1694“.
Though no indication of the varietal name was made
neither on the PACA’s envelope nor on the original
label, this is certainly the material on which the variety
was described, as it grew on Polyporus gilvus Schw. and
the size of the spores indicated in the label is the same as
published by Rick.
= Schizopora paradoxa (Schrad.: Fr.) Donk.
Spores were not found and the hymenium is mostly
collapsed but the hyphal system and pore size strongly
suggest this species.

Remarks: the species comes quite close to Inonotus
pegleri Ryvarden (1975), described from East Africa,
which differs in its larger pores 4-5 per mm, smaller
spores 6-7 pm diam., and setae that may reach 32 pm
wide. It is similar on account of its general macromorphology (massiveness and Phellinus aspect), the
long setal hyphae, the shape of spores and the very few
hymenial setae present (Ryvarden & Johansen 1980).
The spores in I. micantissimus are of somewhat
doubtful origin: they are not typical in shape for Inonotus species and exhibit conspicuous oily contents.
The latter feature recalls chlamydospores and Rick
(1960) described them also as concatenated. But I failed
to find them as such and they were only present in the
tubes and not in the trama and/or context. Their regular
shape and dimensions would point to them being true
basidiospores but I failed to find them attached to basidia.
Rick related the species to Phellinus weirii (Murr.)
Gilbn., but it differs in its dimitic hyphal system, protruding setal hyphae and smaller ovoid thin-walled hyaline spores ( 5 . 5 ~ 4 . 5pm).

The specimen cited by Rick (1960) under the type
variety, i.e. FR 18594 was labelled with the new varietal
name on the PACA’s envelope and in the original label:

Poria subviridis Rick (1937b: 151)
Holotype FR 22630, S. Salvador, 1944: “5.1V.1944, typus”.
= Junghuhnia polycystidifera (Rick) Rajchenberg

This is a previous name for Junghuhnia microspora
Rajchenberg (1983). See there for a description.

collections at PACA.

A small resupinate sample of the species. As it may be
assumed from the label on the original envelope, Rick
probably described this specimen twice, first as Grandinia arachnoidea (Rick 1932) and later as Poria subviridis. This is perhaps the type for Grandinia arachnoidea which Hjortstam and Ryvarden (1982) could not
study.

’hametes isabellina Fr. var. azurea Rick (1960: 260)
Lectotype FR 18685, S. Leopoldo, typus: “In ligno
frondoso, no. 1591”.
= Diplomitoporus lenis (Karst.) Gilbn. & Ryv.
Not validly published since the nomenclatural type was
not indicated in the protologue. A specimen was found
among those cited by Rick (1960) for the type variety o n
which, presumably, the variety was described: FR
19296, sub Trametes isabellina Fr. var. azurea Rick, S.
Leopoldo, 1932: “In ligiio frondoso” and with a latin
diagnosis similar t o that published by Rambo. It is a
sterile and indeterminable poroid resupinate fungus.
FR 18596, which was cited by Lowe (1963) as a synonym of Trechispora regularis (Murr.) Liberta, is probably the same collection he later cited as lectotype
(Lowe 1966). Since it has no indication in Rick’s handwriting that it is a “typus”, such as is the case with FR
18685, this material cannot be considered the lectotype
of P. subvulgaris.
Poria tenui-sulphurea Rick (1960: 284)
Not validly published since the nomenclatural type was
not indicated in the protologue. A specimen was found
that is, presumably, the collection o n which the species
was described: FR 20341, sub Poria?, S. Salvador,
1943: “Poria tenui-sulphurea Rick n. sp., 21 .VII.1943”.
This is Ceriporia viridans (Berk. & Br.) Donk.
Poria velata Rick (1937b: 148)
Selected lectotype FR 18747, Pareci, 1930: “In ligno
frondoso, sp. sphaericis 5 ym”.
= Ceriporia xylostromatoides (Berk.) Ryv.
Lowe (1963) studied FR 18513 which later was presumably referred by him as the lectotype (Lowe 1966). This
collection contains no fungus at PACA, but a label was
found which states: “In ligno frondoso, Sta. Maria,
1936; sp. 3 ~ 2 . ym,
5
asperis, Rick”. T h e measurements
of the spores are not in accordance with those given in
the protologue (“sp. sphaericis, albis, 5 pm”, cf. Rick
1937b) as is the case of FR 18747 label. Therefore, FR
18513 cannot be considered the proper lectotype of P.
velata.
Another collection was studied, viz. FR 18527, Sta.
Maria, 1936: “In ligno frondoso, no. 1658, sp. 3x2.15
