Classification
Descriptions
Minute, black, soon expanded, with a narrow margin, sometimes flexuose. Asci clavate, large; sporidia subcymbiform; endochrome bipartite; paraphyses linear, much longer than the asci.
atra, expansa, margine angusto, ascis clavatis amplis, sporidiis subcymbaeformibus endochromate partito.
Allied to P. atrata, but apparently distinct from all its forms.
On decaying Montia fontana. Ahuriri, Eastern Coast, Colenso.
Cashiella montiicola (Berk.) Dennis 1961
On decaying Montia fontana (Portulacaceae), at the nodes, Ahuriri, Hawkes Bay.
Apothecia sessile, cupshaped, 0.5 mm. diam., black throughout, receptacle smooth, excipulum composed of isodiametric, rounded to angular, thin-walled, dark brown cells, up to 9 x 6 µ, passing into parallel hyphae at the extreme margin only. Asci clavate, 8-spored, 65-70 x 9-10 µ, the small pore blued by Melzer's reagent; ascospores biseriate above, uniseriate below, ellipsoidal, hyaline, nonseptate. 9-11 x 3-4 µ; paraphyses very slender, often forked, tips suddenly enlarged, pyriform, 3-5 µ wide, forming an epithecium.
I feel this species cannot be left in Mollisia because of its forked paraphyses with greatly enlarged brown tips cohering to form an epithecium. I have not seen the type species of Cashiella, C. atra Petrak, and refer the fungus here from his description only, though this does not indicate the iodine reaction of the asci or even, clearly, that they are inoperculate.
