Abstract Eighty-one taxa of myxomycetes collected from Yunnan Province, China are reported.
Among them, 4 taxa, namely, Perichaena verrucifera , Physarum ovisporoides, Trichia crenulata
var. /atitubularis and Didymium melanospermum var. calcipes are new to science, 23 are newrecords for China and 58 are new to Yunnan Province.
Key words: Myxomycetes, China, Yunnan, taxonomy.

Yunnan Province lies between 21 °08 'N and
29° 15 'N. It is recognized as a province possessing the most abundant biodiversity in China.
However, only 52 myxomycetes have been reported from this province up to now (Teng, 1963 ,
1996; Li & Li , 1989; Li et al., 1990; Yamamoto
et al., 2000). They are poor representation ofmembers of the class Myxomycetes. Therefore,
more myxomycetes are expected to be discoveredfrom Yunnan Province.
The present paper is based on a myxomycete
collection made during a botanical expedition to
Yunnan Province organized by the National Science Museum , Japan , in collaboration with theKunming Institute of Botany, Academia Sinica,
China, in 2000. The collection consists of 204
specimens which are classified into 81 taxa. In
the following list, these taxa are alphabeticallyarranged. Among them, 58 taxa are new to Yunnan, indicated by asterisks in the list and 23 taxa
are new to China, indicated by double asterisks.
Specimens cited are kept in the herbaria, National Science Museum, Tokyo (TNS), Japan,
and Kunming Institute of Botany, Academia
Sinica, Kunming (KUN), Yunnan , China, andKanagawa Prefectural Museum of Natural History (KPM), Odawara, Japan. Holotypes are pre-served in TNS and isotypes in KUN.

Ceratiomyxales

I.* Ceratiomyxa fruticulosa (O.F. Muell.) T.

Wulian Mts. , Lingbao Mt. , ea. 2500 m alt., ondead wood, 5 IX 2000, coli. H. Hagiwara).
Although this variety usually forms filiform
branched sporophores, 2000CU-46 has hemisphaeroid to ovoid simple sporophores like C.
fruticulosa var. descendens Emoto. But its
sporophores don 't have the polygonal basal flatmounds which characterize the latter variety.

This species resembles C. cancellata var.
anomala in having a partial peridial net at theupper part of a sporotheca, but it is distinguishedfrom the latter by a much fewer number of ribs inthe sporotheca.

This form is very similar to C. pyriformis var.
notabilis in appearance, but its spores, measuring8.2- 9. lp.m (mean=8.7, sd=0.30, n = 20) in
diam. , are much larger than those of the latter
which are 6- 8pm as reported in Martin &Alexopoulos ( 1969) and Neubert et al. ( 1993).

This new species best fits to P pedata (A . &G. Lister) G. Lister or P vermicularis (Schwein.)
Rostaf. in the key of Keller & Eliasson (1992),
but clearly differs from the latter two in that the
sporocarps of P pedata are stalked and bearsmaller spores measuring 9- 10 pm, and those of
P vermicularis have verruculose peridia. In
China, two species of Perichaena, not referred in
the above key, were hitherto described as new to66

science, namely, P poronema Y. Li & H.Z. Li
from Yunnan Province and P membranacea Y.
Li, Q. Wang & H.Z. Li from Liaoning Province(Li et al., 1990). However, P verrucifera is easi ly
distinguished from P poronema and P membranacea because the sporocarps of P poronema
have double peridia, circumscissile dehiscence bylid, porous capillitium and smaller sporesmeasuring 8- 10 )lm, and those of P membranacea are pseudoaethalioid with much thinnercurved-spinulose capillitium threads measuring

This form is very simi lar to D. simplex, butdifferent in col or and shape of sporocarps. These
characters are somewhat similar to those of D.
rufostriatum Nann.-Bremek. & Lado. However, it
clearly differs in its simple peridium from the latter species with a three-layered peridium . Its systematic position couldn't be decided because of ascarcity of fully matured sporocarps. Therefore, abrief description is given as follows.
Fructification sporocarpous. Sporocarps closely gregarious to crowded, sessile, usually globosewith constricted base, orange-red when mature,dark brown when immature, ea. 0.5 mm in diam .
Hypothallus membranous, brownish, common to
the colony. Peridium appearing single, having
orange-red lime globules, with many clusters ofdense lime granules on the inside . Dehiscence irregular from above. Columella subglobose tohemispheroid, nearly black, occupying 1/3- 1/2
the diameter of sporocarp. Capillitium radiatingfrom the columella, nearly straight or flexuous,
white in reflected light, nearly transparent bytransmitted light, branched dichotomously, sometimes with connecting bars and dark and/or paleaccretions. Spores globose, dark brown in mass,
brownish-gray by transmitted light, rather irregularly verruculose, 10.7-12.1 J.lm (mean= 11.4,
sd=0.43, n=20) in diam. Plasmodium not observed.

This new variety is easily distinguished fromthe type variety of D. melanospermum by its
white calcareous stalk. In appearance the new variety is similar to D. squamulosum (Alb. &Schwein.) Fr. in that it has white calcareous
sporocarps, but its mottled peridium and darkcolumella are characteristic of D. melanospermum.

Physarumovisporum +oides
Etymology:(from the character like P ovisporum) .
This new species is characterized by white toyellowish or brownish fructifications with twolayered peridia, netted capillitia with white lime
nodes, and minutely verruculose spores which
are usually ellipsoid or ovoid in shape. In the
Physaraceae, the ovoid spores chracteristic of thi s
species have been found in only two species,
Badhamia ovispora Racib. and P ovisporum G.
Lister. However, other spore features of P ovisporoides are different from those of B. ovispora

Myxomycetes from Yunnan, Chinaand P ovisporum. Namely, spores of B. ovispora
are indistictly verruculose and larger, measuring(14- ) 16- 18 (- 2l) X(5.5- ) 6- 7 (- 8)J.1m (Keller
et al. , 1975), and spores of P ovisporum are verruculose or spinulose, often marked with palelines on the epispore and measuring 9- 11 .urn
or 12- 13 X I 0- 12 .urn (Martin & Alexopoulos,
1969).

further study. Its brief description is given as follows.
Fructification sporocarpous. Sporocarps gregarious to clustered, sessile to very short-stalked.

black when lime is scanty, ellipsoid, obovoid,
subglobose or irregular, 0.4-0.7 mm in diam ., up

light, covered by dense lime granules. Dehiscence irregular from above. Columella none.
Capillitium netted, somewhat persistent, sometimes limeless; lime nodes angular, orange topale yellow in reflected light, pale orange to paleyellow by transmitted light; connecting threads
slender, nearly transparent, usually expanded at
the junctions. Spores globose or rarely ellipsoid,
dark brown in mass, grayish-brown by transmitted light, irregularly verruculose or spinulose,

Thi s is the second report of L. tuberculosporum in the world, which was originally describedon the basis of a specimen from Colombia (Farr,
1967). This very rare species is somewhat similar
to L. atrosporum Meyl. and L. cristatum Meyl. ,but it completely differs from the latter two in its
episporic markings.

This species is similar to Comatricha ellae
Haerk. in macroscopical appearance, but it isclearly distingushed from the latter by its surface
net, spore size, and episporic markings .
