Podospora longicollis?
Joop van der Lee, 13-04-2019 17:14
A last effort to get an answer on this species, it seems to be quite a problem, so far I found 5 species with asci holding 512 spores in available documentation:
1. P. araneosa: (only in Spain on sheep dung) but no tuffs of agglutinated hair.
2. P. granulostriata: (no tuffs of agglutinated hair)
3. P. eminens: (no tuffs of agglutinated hair)
4. P. curvicolla: (doubtful if they have 512 spores) but having tuffs of agglutinated hair
5. P. longicollis: tuffs of agglutinated hair and measurement fit most of the parts.

Found on roe-deer pallets, 4 species have been analized.

Perithecia: 998-618 um (neck included); neck 210 um wide; body covered with septated, flexuous hairs, 96-196 umx2.2-2.3 um; tuffs of septated agglutinated hairs originating from the base of the neck, 287-304x3.7-4.8 um, thick walls 0.8 um; neck covered with straight, septated hairs 63-138x3.2-3.5 um.

Asci: poly spored; holding 512 spores; clavate but saccate when expanding; 365-398x75-105 um.

Spores: Immature spores dumb-bell shaped 21 um ling; immature spoon shaped spores covered with warts and having solid upper- and secondary caudea; mature spores 19.1-20.9x12-12.5 um; pedicel 10.8-14.2x4.1-4.4 um (at the top); upper cauda solid, septated, 42x3.5; secondary cauda at the end of the pedicel; solid, 40x2.4 um.

Re : Podospora longicollis?

I have asked David Malloch his opinion about my finding and he would call it P. longicollis.

But I will still try to find more species to give better photografic results.

Most of the information I found in Revision of the genus Podospora - Mirza & Cain (1969) CJB 47: 2028
