... for Moscow and Moscow Region. This species is dis tingui shed by long plasmodiocarps, slightly curved, with irregular shape, sometimes heaped (Fig. 5D), yellow, with large nodes of capil litium and small light spores (7-9 µm in diam.) uniformly co vered with small warts. It was previously described as P. vi res­ cens var. nitens Lister. Typical form of P. virescens differs by pseudoaetha lia composed of heaped sporangia, which aggregate in a com pact structure. P. luteolum is ...

... penetrale Rex (Fig. 5G) -168d (22). This unusual species is characterized by thin, membranous, slight ly silvery iridescent peridium, long, thin stalks and long co lu mel la that penetrates the whole sporangium (Fig. 5G), solid ca pil li tium network formed by thin hyaline tubes with compact New for Moscow, Moscow and Tyumen Regions. This species is ve ry similar to P. cinereum, but differs by dark-brown spores with light lines of dehiscence and well-developed warts. For the first time P. spectabile was recorded in the Central Fo rest Natural State ...

... for Russia (Primorye Territory). Description. Sporophores stalked sporangia, clustered in large groups, long, cylindrical, erect or slightly dropping (Fig. 5A), rich rus ty-brown; become dark-brown or black, semi-transparent after spore dispersal, 7-9 mm high; often join and form a struc ture resembling a pseudoaethalium. Peridium evanescent. Hy po thallus well developed, continuous under a colony, mem bra nous, shining, violet-brown. Stalk black, shining, from 1/4 to 1/2 of the total high, ...

... net work. Capillitium forms a dark-brown to almost black net, with copper reflection. Inner network is very lax, arising from the columella by relatively few branches, often flattened, with mem bra nous expansions in the axils. Surface net large-meshed (the mesh diameter is about 8-10 times the spore diameter), ir re gu lar, with many free ends (Fig. 5B-C). Spores dark-brown in mass; smoky-brown in transmitted light; united in clusters of 4-12 or more ( Fig. 4G-H, 5C), often angular from pressure, oc ca sio nally free and then globose; uniformly warted on external sur face of a group and almost smooth inside a cluster (Fig. 4H), 7-8 µm in diam. Plasmodium white before fruiting (Martin & ...
