Hypocrea peltata: a mycological Dr Jekyll and Mr Hyde?

Samuels, G.J., Ismaiel, A., 2011
Mycologia, 103(3):616-30

 Hypocrea peltata (Pezizomycotina, Hypocreales, Hypocreaceae) is a
common, widespread essentially subtropical species, with an
uncharacteristically large stroma and asci containing four large and
four small bicellular ascospores. Its only anamorph consists of
indehiscent aleuriospores; it does not form a Trichoderma anamorph,
which is typical of most Trichoderma/Hypocrea species. Hypocrea peltata
grows very well at 37 C. The large stromata and failure to form a
Trichoderma anamorph could lead one to doubt its generic placement.
However sequences of the internal transcribed spacer region (ITS), 28S
nuclear large subunit (LSU) of rDNA and RNA polymerase subunit II (rpb2)
regions indicate that it represents a unique lineage within
Trichoderma/Hypocrea. ITS and rbp2 sequences derived from cultures of H.
peltata are identical to the "unidentified Hypocreaceae" reported in
the literature as being isolated from lung of a patient with non-fatal
pulmonary fibrosis.
