Crocicreas gramineum

Zotto, i checked this specimen shortly and it similar with your drawings. But you said you are interested in fresh state? (now it is not fresh, but some pictures were done in vital, plus i remember well the place it was collected and may visit it again).

The main difference: there are two types of paraphyses: filiform and lanceolate (I don't think that it is underdeveloped, rather two different).


Apothecia turbinate, short-stipitate, up to 0,5 mm in diametre, 0,5 mm high, outer surface smooth, brown, edge (collar) lighter, narrow, hymenium grayish, concave; growing in dense groups.
Excipulum from textura oblita; asci cylindrical, with croziers, with euamyloid pore, about 50 x 6,5; paraphyses of two types: filiform and lanceolate in one apothecium, filiform scarsely branched, 1,5 mk broad, some enlarged at tips, lanceolate exceeding the asci by 10 mk, up to 3,5 mk in largest part, with 2-3 septa in lower part, may be with thin outbranches; spores ellipsoid, slightly curved, with two big guttules (vital, i suppose it was in water), 10,7 (10-11,8) x 3,3 (3,1-3,5) (N=12).


On dead leaves of Milium effususm, coniferous mixed forest, N61,086961    E69,466226, 12.06.2012.

Re : Crocicreas gramineum
Hi Nina

Incredible! So you did  these vital photos in June on the fresh specimen. The spores are alive, yes, and also the paraphyses look so. Only the asci are all dead.

Could you please send me these images in higher resolution? (zotto@arcor.de) The paraphyses are the important thing I wished to see. In Cyathicula they are always prominently multiguttulate, but here they look eguttulate. That would be a further reason  not to accept the synonymy of the two genera as proposed by Dennis.

There is another species or variety, C. gramineum var. incertellum with slightly smaller spores. In both I saw long and wider, and narrow and short paraphyses.

Did you also check with IKI? The shape of apical ring is different from Cyathicula.

Re : Crocicreas gramineum
Thanks for pics! I was wrong, it was Carpenter 1980 who made the combinations in Crocicreas.

For the identity I feel this group needs restudy. In Dennis 1956 Phialea incertella has spores 6-8 x 1.5-2, too small,  P. stipae (= gramineum) 7-10 x 2.5-3 (with two big oil drops after carpenter), so quite good. There are more names which are possibly synonyms of the other two.

So I would identify your fungus as Crocicreas gramineum. But the three samples I have studied all have these big oil drops.

Re : Crocicreas gramineum
There are are some more pictures (rehydrated specimen),

i noticed that pore RB (lugol + water as well as lugol + KOH); it is with very slight violet tinge, but  not clear blue in some asci.

Re : Crocicreas gramineum
Great! This type of thick-walled apical ring I never saw in typical members of Cyathicula.
